Abstract (en)

A process for applying flux in solid, liquid or gaseous form directly to a solder wave (26) avoids prefluxing of printed circuit boards or other elements (44) to be soldered or solder wetted. The process comprises the steps of forming a solder wave (26) above a solder reservoir (16), applying a flux directly to the solder wave separately from a shield gas delivery means (36) to blanket the solder wave, and conveying the element (44) through at least a portion of the solder wave. The process is applicable to wave soldering under a shroud (32) wherein a shield gas is supplied by diffusers (36) under the shroud, the flux being applied by at least one gas applicator (54) directly to the solder wave. <IMAGE>
